Sure.
The dns r-live-cache.akamaized.net is what DSTV Now resolves to stream the live streams from when watching dstv now. On saturday, most of it, it seems akamai was not only rerouted international, but also there was packet loss during the game. The specific shade of red at the time of the rugby game (18:30 to 20:30), shows around 25-50% packet loss. The packet loss is huge, that is what caused the buffering.
The spike usually doesnt matter, as long as the performance is good and the packet loss is at 0%.
Had I looked at this graph, I would probably have switched dns providers to hopefully get routed to a different cluster.
